Organic light-emitting display panel and display device

An organic light-emitting display panel, comprising:

• a display area;
• a plurality of organic light-emitting components located in the display area;
• a pixel defining layer located in the display area, wherein the pixel defining layer comprises a plurality of aperture regions, each of the plurality of aperture regions corresponds to one of the plurality of organic light-emitting components;
• and
• a color resist layer located at a light-emitting side of the plurality of organic light-emitting components, wherein the color resist layer comprises a plurality of color resists corresponding to the plurality of aperture regions and a plurality of black resists located outside the plurality of color resists in the display area, and
• wherein one of the plurality of color resists has a same color as one of the plurality of organic light-emitting components corresponding to one of the plurality of aperture regions,
• on a plane where the organic light-emitting display panel is located, an area one of the plurality of color resists is smaller than an area of a corresponding one of the plurality of aperture regions, and
• on the plane where the organic light-emitting display panel is located, a length of any side of one of the plurality of color resists is d times a length of a corresponding side of a corresponding one of the plurality of aperture regions, and 0.5<d<0.7.
